World cup soccer players tend to be born with sun and moon in adjacent zodiacal signs.

“The ecliptic elongation of the moon with respect to the sun does not show uniform distribution on the birth dates of the 704 soccer players selected for the 1998 World Cup. However, a uniform distribution is expected on astronomical grounds. Read More

Once reserved for those who couldn’t pay their electricity bills or wanted to grow weed inside, snagging some free power via grappling hook is now a military operation. As described on the National Defense Education Network website, the Air Force has designed a “Bat Hook” which soldiers can heave into the air — action-hero style — to steal some juice from suspended power lines.

“We work very closely with Special Operations,” says Dave Coates, lead engineer on the project at Wright-Patterson Air Force Base (in the video below, and as shown by Popular Science). Their request? “Is there a way that you could possibly give us something like Batman?”

The Bat Hook system, technically called Remote Auxiliary Power System (RAPS), pierces the power line’s insulation to draw current directly where it’s needed, to charge batteries on the ground, for example.

“Peacekeeper” missiles are getting a new lease on life: as satellite launchers. Next week, the Air Force plans to launch the second of these decommissioned intercontinental ballistic missiles, renamed “Minotaur IV,” to deploy a trash-tracking satellite.

It’s nice to know that one relic will help us spot others–pieces of junk, like abandoned rocket stages left over from other space missions. As the IV in the new rocket’s name implies, the Peacekeeper isn’t the first retired missile to enter the Air Force’s very special recycling program. The first Minotaurs (pdf) incorporated stages from Minutemen missiles.

Barron Beneski is a representative of Orbital Sciences Corp., which holds the Air Force contract to transform the missiles into launch vehicles. Beneski toldDiscovery News:

“What is neat is that what was once a military weapons system is now a peaceful use of government assets. It’s the whole idea of turning ‘swords into plowshares.'”

Other countries, notably Russia and China, have similar missile makeover programs. Unlike these countries, the United States does not offer the boosters for sale on the open market–only for government use.

Emotional contagion in soccer penalty shootouts: Celebration of individual success is associated with ultimate team success.

“We examined the association between celebratory responses after successful soccer penalty kicks and the outcome of a penalty shootout. Individually displayed post-shot behaviours in penalty shootouts held in World Cups and European Championships (N = 151) were rated on the presence of universally distinct and recognizable behaviours associated with positive emotions.

Would you eat honey called Dulles Delight? LAX Natural? LaGuardia Lip-Smackers? Some Germans are enjoying Düsseldorf Natural, honey made from airport-dwelling bees. The Düsseldorf International Airport and 7 other airports have employed bees as “biodetectives”: inspectors test the bees’ honey for pollutants as an indirect way to monitor airport air quality.

As The New York Timesreports, these bees come from a long line of other insect inspectors–including aquatic bugs for testing water quality. Though the airports still use more-traditional sensors to test for air pollutants, in 2006 they added these buzzing mini-inspectors to their testing fleet.

The German Orga Lab tests the honey, made from around 200,000 bees, twice a year for contaminants such as hydrocarbons and heavy metals. They hope to monitor changes over long stretches of time to see if the bees can pick up air quality differences.

Martin Bunkowski, an environmental engineer for the Association of German Airports, told The New York Times that the project is appealing because the insects’ job seems clear.

“It’s a very clear message for the public because it is easy to understand,” Bunkowski said.

Currently, the Düsseldorf honey is looking good–contaminants were far below official limits, and the honey was comparable in quality to that harvested in more scenic locales. Most importantly, since the local bee club gives the honey out for no charge, the sweet stuff is effectively duty free.

We showed the (successful) attempt to blend the iPad in April. Now the blender company Blendtec–which has also destroyed glow-sticks and various Guitar Hero iterations–has tried the same with Apple’s newest toy:

Admissions for myocardial infarction and World Cup football: database survey.

“OBJECTIVES: To examine hospital admissions for a range of diagnoses on days surrounding England’s 1998 World Cup football matches. DESIGN: Analysis of hospital admissions obtained from English hospital episode statistics. SETTING: England. PARTICIPANTS: Population aged 15-64 years. MAIN OUTCOME MEASURES: Ratio of number of admissions for acute myocardial infarction, stroke, deliberate self harm, and road traffic injuries on the day of and five days after England’s World Cup matches, compared with admissions at the same time in previous and following years and in the month preceding the tournament.

It’s a happy ending for Oscar. While lazing in the sun, the British cat lost his two hind paws in a tragic combine harvester accident. But after receiving two bionic paws from Noel Fitzpatrick, a veterinary surgeon based in Surrey, the lucky black cat can now continue crossing many paths.

Here’s the situation: You spot Roman attack ships headed for your shores. Do you order your troops to ready the cannons? Or–in an ancient MacGyver move–do you use a parabolic mirror, focusing the sun’s rays to set the ships on fire? Though the latter is clearly more suave, recent research has shown that the 212 B.C. legend about Archimedes’ mirror defense is unlikely: He probably pulled out the big guns instead.

Cesar Rossi, a mechanical engineer at the University of Naples in Italy, figured out the numbers. A steam cannon–like the ones Leonardo da Vinci drew in the 1400s–could use less than a tenth of a cup of water to fire a hollow clay ball, at 134 miles per hour, to hit a target 492 feet away. For comparison, an 1854 American Civil War Howitzer cannon could fire a ball about ten times farther–a little less than a mile.

Case report: Ectopic nipple on the sole of the foot, an unexplained anomaly.

“Supernumerary nipples are common congenital anomalies, most often occurring along the embryonic milk lines. We present a patient with an ectopic nipple on the foot. We are unable to explain the aetiology of this anomaly; however, several theories have been proposed.” Read More
